The BBC bosses have since responded to the claims and have admitted to recreating some of the sounds in the studio.

They do this to “create a sense of a wild place, as well as emotion and drama” according to the Sun.

Range and ambient noise ensure quite a lot of wild sounds simply cannot be recorded in the field. As a result, wildlife film-makers often turn to sound designers to recreate something that sounds like it would in the wild - a soundtrack that is true to nature.
